, which the following is a specification.

The especial object of my invention is to provide an improved form of lantern base adapted to hold an inverted globe and which will not produce a shadow or obscure the ground directly beneath the lantern, as oc curs with the ordinary lantern having a' solid base.

It is also an object of my invention to provide for the easy insertion and withdrawal of the globe from my lantern base; and to provide a lantern base which'xnay be constructed at relatively small expense.

It is also an object of my invention to combine my base with lighting means of the acetylene type. having mechanical lighting means.

I attain the objects of my invention by the mechanism illustrated inthe accompanying drawings, in which Figure 1 is a side elevation, with a portion of the globe broken away to show the burner; Fig. 2 is a plan section looking down from line 22 of Fig.1, with globe re moved.

Like characters of reference indicate like parts throughout the several views.

Referring to the accompanying drawings, I provide an annular base member 1 secured to which are a plurality of standards 2 supporting a globe-supporting ring 3, to which are secured a plurality of lamp-supporting standards 4 secured to a suitable acetylene lamp 6, and supporting a disk 5 spaced below the lamp. Suspended from ring 3 by metal straps 8 is a globe-supporting ring 10, one of the straps being provided with a catch portion 9 adapted to releasably engage ring 8, as shown in Fig. 1. The acetylene burner 7 is provided with a suitable mechanical lighting device 12, operated by a suitable wire 13, which may be eXtended to a point above the globe 11, to light the device without removing the globe, by pulling the Wire 13 and projecting sparks over the' burner. Any suitable mechanical lighter may be utilized, and I do not claim. this Specification of Letters Patent.

element as my invention. To remove the globe, catch portion 9 is released from its engagement with ring 3, and the globe supporting ring 10 lowered in the manner indicated in dotted lines in Fig. 1. As disclosed in Figs. 2 and lyring l is of larger size than ring 3 and than the globe 11, so as to permit of the removal of the globe through the base ring 1, as will be readily understood after noting the drawings. The globe 11 is of the inverted type, thus fully protecting the burner and throwing light in all directions, vertically as well as laterally, so that no shadow interferes with the usefulness of the lantern.

ll'hat I claim is:

1. A shadowless lantern base comprising an annular base member, standards attached" thereto supporting a globe encircling ring,

standards secured to the globe encircling; ring supporting a lantern tank having a burner depending therefrom, an inverted globe encircling toe burner, and a globe supporting ring releasably supported from one side of the globe encircling ring, and non-releasably supported from the opposite side, substantially as disclosed.

2. An acetylene lantern comprising an acetylene tank, a burner depending therefrom and having mechanical lighting means operable without removal of the globe mem her, a plurality of standards supporting the tank and supporting a disk spaced below the tank, a. globe encircling ring to which the standards are engaged,a base ring of greater diameter than the globe-encircling ring,

standards supporting the globe encircling ring from the base ring, an inverted globe insertible through the base ring, a globesupporting ring to retainthe globe in place, a strap connecting the globe-encircling ring" with the globe-supporting ring, and an oppositely disposed strap having a catch portioh releasably engageable with the,globesupporting ring, whereby to provide a shadowless lantern base into which an inverted globe may be readily inserted and removed.
